Filmmaker Errol Morris discusses his famed interview device, the interrotron, which allows the subjects of his films to maintain eye contact both with the camera and him during the interviews. He used it to great effect for the Oscar-winning Fog of War and his new movie, The Unknown Known. When Morris isn't deep in the midst of a film he can be found directing commercials. He boast a thousand ads directed, and his dirty little secret is...he loves it. Plus, what does he think of Twitter?

With all the talk recently about runaway production Graham Yost talks about making Justified in California. The FX show is set in Kentucky but is shot in Los Angeles because Timothy Olyphant, the star, wouldn't do it anywhere else. The show gets production incentive money from the state to offset costs.
